Question pzstd popuser high CPU-usage

[pwouda]

Server operating system version

CentOS Linux 7.9.2009 (Core)

Plesk version and microupdate number

Plesk Obsidian 18.0.72 Update #3 Web Host Edition

Hi,
Since a few days I noticed my server was slow. Checking the process-list, I found that the process "pzstd" form user "popuser" takes a lot of CPU-usage.

What is the pzstd-process, and wat can I do about this process taking so much cpu-usage?

Best regards,
Peter

I think the pzstd process belongs to a backup / restore . Do you have very large sites on the server?

@pwouda , @cyberjam is right. pzstd is a compression process used by Plesk for backup-related tasks. There is likely a scheduled backup task that runs when you notice the spike, which is expected during backup creations/restorations.
